You need to do a video on Quantum Entanglement.
Can you elaborate on 19:20 ?
How do we know that the particles will still probably be spinning in the
opposite direction assuming that the Universe knows the result?
Why does it feel like quantum physicist are philosophic rather than
physicists? How can theorists argue that the universe cares ever so little
if a phenomenon is observed or not? I am still baffled by this concept. Yes
it is interesting to ponder on the probability that something could have
even if given as little as two choices (two keyholes) but surely there’s a
more objective explanation that has yet to be found, but not, “different
stuff happen if we open our eyes than when we close them”…the universe
doesn’t care if you have your eyes closed or opened.
Balls….
I don’t see what’s strange about there being no correlation between the
measured spin when the detectors are offset by 90 degrees. It seems to me
rather obvious that if one detectors is measuring if its top or bottom the
direction of the spin can be in 4 different “quadrants” all equally likely.
I’d expect the probability of the detectors showing the opposite result to
be (1-Offsetdegree/180degrees) at 90 degrees it’s 50% and at 0 degrees its
100%.
what I find most interesting on this, and please correct me if i’m
interpreting it wrong, is that although an observation of the particles
while they’re doing their movement may impact the probability of where they
hit, an observation of the aftermath does not. one would think that a mere
observation of the aftermath, would make it so that we can determine where
it went and not see the wavelike effect. It makes you wonder what that
implies about if a tree were to fall in the woods and nobody is around –
the probability of where it would land and/or whether or not if ever fell
at all. The tree is encompassed of higher level energy – but still lol
Great video, I’m glad the kitty made it through the whole thing without
being put in a death trap.
Hold on! Doesn’t this explain gravity? If more objects packed into one area
of space cause the probability of being in that position to increase, then
the closer to that object you are the more influenced you are to get even
closer. The more interference patterns there are, the higher the
probability of being closer to the source of those interference patterns.
This change in probability causes energy sources to naturally sync up with
each other. But because of the Pauly Exclusion Principle, the states of
matter wont share the same location creating the phenomena of space and
depth. In short, gravity is acting like a countless dice rolls where the
‘house’ (Mass) usually wins. And the direction of the future behaves like
the direction of the net earnings, which is towards the ‘house’ (Mass).
I always rewatch this experiments and always get amused like a child :))
how more proof scientists need to realise that the reality is an illusion
formed by our own consciousness? We always think that everything around
exists separately from us, but i think its the biggest delusion that face
humanity. Everything religion says, everything metaphysics says, everything
psychology says – modern science just beginning to realise is probably
truth. I am waiting for all studies to unite in one, this would be new age
for a human kind.
PS. and i dont agree that universe ‘desides’ something .. I think that its
just what our perception able to seedetect from an infinite amount of
variations under current conditions… it, sort of, chooses what more
likely we will see from all those possibilities. This also explains why all
people see equally the same (more or less) realities. This could be what
Carl Jung called ‘collective unconscious’.
How do the spin detectors work? How do we know that the particles aren’t
created with perfectly opposite spins and that the detectors make the
particles one of the spins they read (Like a magnet would turn to face the
pole of another) just which ever one is closer? Consider just two
dimensions so I can explain. The detectors are up and down. If the spins is
like 10 degrees and the machine snaps it to perfectly straight up, it
follows that the other’s spin is 10+180 degrees and will be snapped
perfectly down. This also would explain why when the machines aren’t
properly aligned you get bad results.
At 9:35 the video says that both waves still exist as they pass through
both detectors, but in a different state that prevents them from
interacting with each other. I always thought that what was happening was
that the wave was collapsing as it interacted with the detectors, and then
a new wave at that instance was created in the vicinity of one of the
slits. I dunno.
I think you’ll be confusing some people into thinking that it is a human
observation that turns a probablility wave into a determined result. It’s
not. It’s just any measurement inherently changes the particle and now the
probability function is a definite result.
Something doesn’t seem right… how can physics and the actions of
particles change just by observing it?
It makes little sense.
Perhaps I don’t exactly understand what is happening. :/
I was starting to get scared at around 9:30, as someone new to all this,
nothing was making sense…
Wouldn’t incessant observation by a nosy cat permanently collapse the wave
functions, thus destroying all of the experiments being demonstrated in the
video?
Quantum Physics has many loopholes,information that would be really helpful
in solving problems related with it. But we have not advanced to that point
yet, only time will solve these mysteries or will it?
What does all this mean? “Unsolved” says the video, but several Nobel
prize winners have strong opinions about the implications. Einstein:
“Reality is merely an illusion, albeit a very persistent one…Space is not
anything given in nature or independent of human thought [space is a
function of mind]. Space as conceived by Newton proved to be an
illusion…It will remain remarkable that the very study of the external
world led the scientific conclusion that the content of consciousness is
the ultimate universal reality.”
Max Planck: “I regard consciousness as fundamental. I regard matter as
derivative of consciousness.” And, “There is no matter as such… This
Mind is the matrix of all matter.
Werner Heisenberg: “Science has decided in favor of Plato. The smallest
units of matter are not physical, but forms.”
Richard Feynman: “It was a shocking discovery of course that Newton’s laws
are wrong…All that we know can be wrong.”
How do we know life isnt just as we see it? What if life has no explanation
for anything? We just have to wait and see. Death maybe the only place true
answers lie. For that reason, I will just live my life as I do.
The surviving world won’t really ever know. Kind of why I love life;
mystery.
All this stuff is interesting (not that I comprehend even half of it)
though. I love hearing peoples different opinion on the subject.
I did the exact same experiment. When i shot the two marble size balls, and
larger size balls through the two wholes at the exact same time. The always
hit the same spot no matter what. I had the balls mechanically released so
they left at the same time. Do it urself u will see.
Great Video with some very nice explanations here, however at 21:44 do not
forget about coherence. Observers are not entangled with particles unless
they themselves are constrained by quantum mechanics. A classical observer,
such as a human, would not be able to become entangled with the quantum
state of the particle so it is not the observer influencing the outcome, it
is the detector. Also, the detectors are not themselves entangled, rather
the information regarding their polarization orientation in the detection,
what is referred to as the Bell-state measurement, is what is entangled.
Entanglement experiments where the detection apparatus acts on each
particle independently from the state or evolution of the other, and
where each particle is localized at a particular detector registering a
“click” to indicate that a particle has been detected, offer the highest
cross section of detecting entangled particles however they cannot realize
a complete Bell state measurement due to the fact that they are not
constrained by quantum mechanics entirely and incoherence occurs.
In a sense you have to make the entire detector operate on quantum rules,
creating a hyper-entangled state. Bose-Einstein Condensates could do this
and would result in the detector being truly entangled with the
individually entangled particles.
This would also allow for, if both detectors were BECs, a shortcut to
near-macroscopic teleportation where you could teleport both detectors
across the entanglement channel. This would allow for superdense coding of
quantum systems.
This is an invitation to see an artist theory of the physics of ‘time’ as a
physical process. In this theory the extra dimensions of String Theory and
parallel universes of Hugh Everett Many worlds interpretation are just
future possibilities and opportunities in our one three dimensional
Universe of continuous energy exchange or what I like to call continuous
creation!
A Revolutionary Theory for the twenty first century
The universe… knows?
*Excellent narration and animations. I use videos like this to help myself
and students comprehend the mechanics of telekinesis. Adding this one to my
favorites and looking forward to more. Namaste*
8:30 If you put a detector in the back of each hole, it behaves as a
particle? Is there an actual experiment that confirms this?
You are also saying that putting just one detector in front of 1 hole also
causes a particle behavior.
What if you have 1 detector in front of both holes?
